Intel® Media Server Studio HEVC Software Encoder Quality Evaluation for 4:2:0 8-bit Content In this section, we first describe a test methodology employed for evaluating quality and then report on relative quality measurements for the Media Server Studio HEVC Codec with respect to MPEG HEVC HM14 Codec, well known as a high quality reference albeit impractically slow. Deliver High Quality, High Performance HEVC via Intel® Media Server Studio Quality Evaluation Tests for 4:2:0 8-bit Content For the purpose of quality evaluation, four test sets, one for each of the 4 main resolutions are selected with each test set consisting of 6 publicly available challenging video test sequences. Further for each test sequence, 4 well-spaced quantizer (QP) values are selected such that HEVC encoding for each sequence generates bit-rates in a wide but moderate range, avoiding extreme values. Wherever possible, test sequences that are available in multiple resolutions are selected for each test set such that the behavior of a codec over multiple resolutions can be tracked. Specifically, Table 0A shows selected Ultra Definition 4K (UHD4K) test set, Table 0B shows High Definition 1080p (HD1080p) test set, Table 0C shows High Definition 720p (HD720p), and Table 0D shows Standard/Extended Standard Definition (SD/XD) test set.
